Application filed January 6, 1913.

T0 aZZ whom it may concern:

Be it known that I, VVALTER S. MILLER, a citizen of the United States of America, residing in the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Trucks, of which the following is a specification.

The primary object of this invention is to provide means whereby the transom bars are interlocked with the arch bar spacer casting. a

A further object is to provide means whereby the transom bars are strengthened in their interlocked position with the spacer bar casting by the arch bars.

A further object is to provide means for interlocking the transom bars with the arch bar spacer casting, said bars and spacer casting being reinforced by the arch bars so that a very strong and rigid connection can be made between the aforesaid parts.

Other and further objects will appear in the specification, and be specifically pointed out in the appended claims, reference being had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a plan view of a portion of a truck frame, showing this improvement applied thereto. Fig. 2 is a side elevation of Fig. 1. Fig. 3 is an enlarged horizontal view, partly in section, taken on the line IIIIII, Fig. 2. Fig. 1 is an enlarged rear sectional elevation, taken on the line IV IV, Fig. 3. Fig. 5 is an enlarged vertical section, taken on the line V-V, Fig. 3. F ig. 6 is an enlarged vertical section, taken on the line VI-VI, Fig. 3. Fig. 7 is a perspective view, showing one of the interlocking transom bar ends.

Referring to the drawings: 1 designates the wheel of a truck, having the axle 2 which is supported in the usual boxing 3. Mounted on said boxing, adjacent its ends, is a tension arch bar 4. Mounted on said bar 4 is the compression arch bar 5. Supported by said arch bars 4 and 5, adjacent the center, is the arch bar spacer casting 6, which spacer casting, along with its opposite (not shown), carries the transom bars 7.

The transom bars 7 have formed at their ends right-angle tongue portions 8, which tongue portions are out down at the upper Specification of Letters Patent.

and lower edges thereof, as shown at 9, forming shoulders 10 (as shown more clearly in Figs. 3 and 7 Formed integral with the arch bar spacer casting 6 are cheeks 11, said cheeks extending at right angles from said arch bar casting (5. The arch bar spacer casting has a main body portion 12. Formed on the inside of said main body portion are recesses 13, said recesses being formed adjacent one end of each check 11, and extending at right angles therefrom (see Fig. 3).

In order to provide means for securely seating the compression arch bar 5 to said spacer casting 6, a vertical lip 14 is formed, extending longitudinally of said spacer casting and on the outside thereof. Oppositely disposed from said lip 14, and formed adjacent the center of said spacer casting, is another lip 15, said lip extending longitudinally between the recesses 13. Formed on one end of each of said cheeks 11 is a shoulder 16, which shoulders are in longitudinal alinement with the inside edge of the lip 15. I

The tension arch bar 4, which is fitted to the under side of said spacer arch bar casting 6, is taken care of similarly to the compression arch bar 5, as there is a longitudi nally extending lip 17 which depends from said arch bar casting. Oppositely disposed from said lip 17, and in vertical alinement with the lip 15, is another lip 18, which lip is similar to said lip 15. The checks 11 have engaging shoulders similar to the shoulders 16 which are on the upper side of said arch bar spacer casting 6.

In mounting this improved construction together, the tongues 8 of the transom bars are engaged in the-recesses 13, said recesses being of such a length as to just take in the length of the tongues 8, so that a perfectly tight fit will be assured, and the outside side walls 19 of said transom bars will engage against the inside portions of the cheeks 11. The transom bars 7 are secured to said cheeks 11 by the bolts 20, and the tongue portions of said transom bars are engaged against the body portion 12 of said arch bar casting by the bolts 21.

From an inspection of Fig. 3, it is readily seen how a very rigid construction is made between the transom bars and the spacer castings. But in order to further secure the rigidity of said transom bars to said spacer castings, the manner in which the tension and compression arch bars 4 and 5 are seated on said spacer casting will provide means for interlocking the transom bars, spacer casting, and arch bars together.

As shown best in Fig. 5, the cut-down portions 9 of the tongues 8 of the transom bars are flush with the top and bottom of the spacer bar casting so that when the arch bars 4 and 5 are clamped into place by the bolts 22, the horizontal portions of said arch bars will bear against the portions 9 of said transom bars. Furthermore, the inside side portions of said arch bars will lock tightly vagainst the shoulders 10 of said transom bars. Furthermore, the lips 14, 15, 17 and 18, along with the shoulders such as 16, will very firmly secure said arch bars against any oscillating movement.

This construction is designed to provide an improved interlocking transom bar connection with the arch bar spacer castings. From this improved manner of securing said parts together, it is readily seen how a very strong and secure unison of these parts can be obtained.

What I claim is:

1. The combination of an arch bar spacer member, and a pair of transom bars, the ends of said transom bars having rightangled bent portions bent toward each other, and recesses formed in said spacer member for the reception of said right-angled end of said transom bars.

2. The combination of an arch bar spacer member, and a pair of transom bars, the ends of said transom bars having rightangled bent portions, said right-angled portions being cut away forming tongues, and

recesses formed in said spacer member to receive said tongues.

3. The combination of an arch bar spacer member, and a pair of transom bars, the ends of said transom bars having rightangled bent portions, recesses formed in said spacer member for the reception of said right-angled ends of said transom bars, and right-angled portions extending from said spacer member for engaging the outside walls of said transom bars.

4.

8. The combination of an arch bar spacer member, and a pair of transom bars, the ends of said transom bars having right angled bent portions, said right angled portions being bent toward each other, and engaging surfaces formed on said spacer member adapted to bear against said right angled ends of said transom bars.
